摘要: Large-area ferroelectric nanodomain patterns, which are desirable for nonlinear optical applications, were generated in previously He-implanted lithium niobate crystals by applying voltage pulses to the tip of a scanning force microscope. The individual nanodomains found be uniform size, depended only on inter-domain spacing and pulse amplitude. We explain this behavior electrostatic repulsion poling-induced buried charges between adjacent domains. domain patterns imaged piezoresponse microscopy investigated domain-selective etching conjunction with focused ion beam followed electron imaging. In order optimize He-irradiation parameters easy reliable patterning series samples subjected various irradiation fluences energies was prepared. different characterized investigating wide range (amplitude duration). addition, these experiments clarified physical mechanism behind facile poling measured He-irradiated crystals: damage caused energy loss that takes place via electronic excitations appears act stabilize domains, whereas nuclear-collision degrades crystal quality, thus impedes generation.
